Question: Experiment title: Determination of Nickel by Gravimetric Analysis. Objectives:
1. To determine the amount of nickel in a given salt.
2. Calculate the weight percent of nickel in the salt and compared with theoretical.
3. To study the gravimetric analysis method in determine compound in certain given unknown salt.
Answer: Gravimetric analysis is a technique through which the amount of an analyte (the ion being analyzed) can be determined through the measurement of mass. Gravimetric analyses depend on comparing the masses of two compounds containing the analyte. The principle behind gravimetric analysis is that the mass of an ion in a pure compound can be determined and then used to find the mass percent of the same ion in a known quantity of an impure compound. In order for the analysis to be accurate, certain conditions must be met:...(short extract)
